Exo-Civilizations –“It’s Time to Take the Existence of Aliens Seriously”

 

"Awakened" --Unknown Objects Detected Orbiting Milky Way's Central Black Hole

 

Two of our planet’s leading astrophysicists say it’s time to get serious about aliens: Adam Frank of the University of Rochester and Andrew Siemion, director of the U of California Berkeley SETI Research Center, who wrote in an email that “I suspect there are other intelligent civilizations in the Milky Way – we just need to look!” But, asks Frank, will they, or have they, survived their Anthropocene bottleneck?

Water Worlds of the Milky Way –“Not Life as We Know It” 

 

Water World

 

“These are utterly different worlds compared to our own Earth,” said Harvard University astronomer Li Zeng about the chances that water worlds are a common feature of the Milky Way, which was heightened by research using computer simulations showing that sub-Neptune-sized planets, that is, planets featuring radii about two to four times that of Earth, are likely to be water worlds, and not gas dwarfs surrounded by thick atmospheres as conventionally believed.

Earth’s current technological civilization is a model for alien-planet evolution, observed SETI Institute astronomer, Seth Shostak “But having now looked for signals for 50 years, we are going through a process of realizing the way our technology is advancing is probably a good indicator of how other civilizations – if they’re out there – would’ve progressed. Certainly what we’re looking at out there is an evolutionary moving target, If AI-powered machines evolved, we would be more likely to spot signals from them than from the “biological” life that invented them,” he added.

“Alien Beacons” — Radio Astronomers Target C-Band Signal from Artificial Interstellar Technology

ESA LaSilla Observatory

 

Astronomers are targeting the radio frequency range between 4 and 8 gigahertz, dubbed the C-band, said Breakthrough Listen principal investigator, astrophysicist Andrew Siemion of the University of California, Berkeley, who announced the release of nearly 2 petabytes of data, the most comprehensive survey yet of radio emissions from the plane of the Milky Way Galaxy and the region around its central black hole, the second data dump from the four-year old search for extraterrestrial intelligence (SETI).
